Description

Technical Field

[0001] This utility model relates to the field of workpiece assembly equipment technology, and in particular to an automatic hollow pin pressing device and system. Background Technology

[0002] In the manufacturing process of automobile engines, the press-fitting of the hollow pins in the engine housing is a crucial step, and its quality directly affects the overall performance and quality of the engine. The precise press-fitting of the hollow pins into the engine housing plays a decisive role in ensuring a secure connection between engine components and efficient power transmission.

[0003] Currently, the vast majority of automobile manufacturers still use the traditional manual operation method for the press-fitting process of hollow pins for engine housings. For example... Figure 1 As shown, the detailed operating procedure is as follows: First, relying on their own operating experience, the worker carefully places the engine housing onto the positioning fixture using both hands. This step requires a high degree of skill and concentration from the worker; even a slight deviation in the placement of the housing will severely affect subsequent pressing processes. Next, the worker needs to manually and precisely fix the hollow pin into the corresponding position on the housing. This process not only requires the worker to have a high degree of patience and meticulousness, but also makes it difficult to ensure that the position and angle of the hollow pin are completely consistent every time it is fixed manually. Finally, the worker manually presses down the press to press the hollow pin into the engine housing.

[0004] However, this manual hollow pin press-fitting process exposes several significant drawbacks. From a production efficiency perspective, because every step of the press-fitting process relies on manual labor, the complex and tedious operations result in a lengthy and extremely inefficient installation process. In the context of modern large-scale automobile production, this inefficient press-fitting process simply cannot meet the demands of high-efficiency and rapid production. Regarding installation quality, manual operation of the press makes it impossible to precisely control the applied pressure. On the one hand, there is a high possibility of the hollow pin not being installed properly, resulting in an insufficiently tight connection between the hollow pin and the engine housing. During high-speed engine operation, this weak connection may cause components to loosen, affecting the coordinated operation of various internal engine parts, and in severe cases, even leading to engine malfunction. On the other hand, if workers apply excessive force when operating the press, the hollow pin or engine housing can easily be damaged, leading to product scrap and significantly increasing production costs. Furthermore, manual operation is significantly affected by individual worker differences. The varying operating habits, force control, and proficiency of different workers make it difficult to ensure product consistency, severely restricting the stability of automotive engine product quality. With the rapid development of the automotive industry, market demands for engine production efficiency and quality are becoming increasingly stringent. The existing manual hollow pin press-fitting process has become a prominent obstacle to further improving engine production levels, urgently requiring the development of a new, more efficient, stable, and reliable press-fitting process to address this issue.

[0005] Currently, no effective solutions have been proposed for the problems existing in related technologies, such as low installation efficiency, inability to guarantee installation pressure, poor product consistency, low product yield, easy misinstallation of hollow pins, and damage to the casing due to excessive pressure.

[0251] At the press-fitting station, the second vertical motion mechanism 330 operates, driving the adsorption mechanism 340 to move downwards to press the hollow pin into the workpiece.

[0252] After the pressing is completed, the adsorption mechanism 340 releases the adsorption of the hollow pin, and the second vertical motion mechanism 330 works to reset the adsorption mechanism 340.

[0253] The first transverse motion mechanism 110 operates, driving the first bearing mechanism 120 to move, so as to transfer the assembled workpiece to the workpiece loading station;

[0254] Repeat the above steps until the hollow pin assembly of all workpieces is completed.

[0255] The technical effects of this embodiment are as follows:

[0256] 1) The press-fitting fixture is automatically assembled using a single-axis robot (i.e., the second vertical motion mechanism), which ensures the consistency of product assembly;

[0257] 2) The pressing operation is automatically pressed by a servo press, and the pressure and displacement range can be set to achieve high-precision pressing of products and improve the pressing yield of products;
